settings.xml没有配置插件应此需要

[sql] view plaincopyprint?

1. mvn org.mortbay.jetty:maven-jetty-plugin:run   

这样来运行。
如果需要使用jetty:run,那么必须在maven的setting.xml下配置

[plain] view plaincopyprint?

1. <pluginGroups>  

2.     <pluginGroup>org.mortbay.jetty</pluginGroup>  

3.   </pluginGroups>  

或者在对应项目的pom.xml中plugins的节点下添加配置

[sql] view plaincopyprint?

1. <plugin>  

2.                 <groupId>org.mortbay.jetty</groupId>  

3.                 <artifactId>jetty-maven-plugin</artifactId>
